LAMP' ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 726,525, dated April 28, 1903. Application filed July 2.` 1902. Serial ITO. 114,078. (No model.)

nying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel lamp attachment whereby the filling of an oil-lamp may be readily and quickly effected without interference by the depending portion of the wick, the burner being so mounted on or connected with the lamp-bowl or oil-reservoir as to be swung back for lling purposes, at such time the wick being moved over close to one side of the filling-opening. I have also provided means for eifectually preventing the escape of oil or -vapor between the iixed and movable parts or members of the connection between the burner and the lamp-collar.

The various novel features of my invention will be hereinafter described, and particularly pointed out in the following claims.

Figure 1 is a side elevation of a lamp attachment embodying one form of my invention, the burner being swung back for the purpose of filling the lamp-bowl. Fig. 2 is a front elevation thereof; andFig. 3 is a vertical sectional viewA of the deviceV on the line com, Fig. 2, the burner being shown, however, as shut down or closed in normal position.

The lamp-bowl or oil-reservoir A, shown onlyin part, the lamp-collar AX, permanently secured thereto surrounding the filling-opening and having an internal screw-thread dx, Fig. 3, and the burner comprising the tubular or sleeve-like body B, deiiector or hood B',and wick-tube B2,may be and are all of substantially usual or well-known-construction. In my present invention, however, thelower end of the wick-tube is extended very slightly beyond the lower face of the bottom h of the body, as at b2, and said bottom is provided with a series of external annular corrugations bx adjacent its periphery, for a purpose `to be described, said corrugations being shown in Figs. 2 and 3. The corrugations may be formed by stamping, pressing, or in any other suitable or convenient manner. A

coupling sleeve or connection C has secured to it a hinge-loop or similar device c to receive a pintle b, attached to the body of the burner, the latter being provided at a point substantially diametrically opposite the hinge with a spring-catch h3 to coperate with a pin or projection c3 on the coupling C. The lower end of the latter is externally screw-threaded at CX to cooperate with the thread dx of the lamp-collar, and thereby connect the lat- `ter and the coupling in a strong and rigid manner. At its upper end I have shown the coupling C provided with an inturned flange c5, which is annularly corrugated in such manner that the ribs or grooves thereof register with or are opposite the grooves and ribs, respectively, of the corrugated portion X of the burner-body, as clearly shown in Fig. 3, when the burner is in closed or operative position. At such time the springcatch h3 is engaged and held by the projection c3, and the two sets of annular corrugations seat squarely and closely one upon the other, so that an oil and vapor tight joint is provided between the body of the burner and the coupling, preventing any leakage of oil to the exterior of the attachment and preventing escape of vapor from the lamp-bowl.

To fill the lamp,`the catch b3 is released by the finger and the burner is swung back on the hinge connection between it and the coupling C, and the edge of the chimney-holder B3 by engagementwith the` exterior of the lamp-collar, as shown in Fig. l, maintains the bottom b of the burner-body substantially vertical and at the extreme edge of the coupling C. This, in connection with the short end of the wick-tube, brings the depending portion of the wick close to the side of the coupling, leaving the greater portion of the opening therethrough free and unobstructedfor filling; but the wickis held away from the interior of the coupling, so` that oil will not be deposited thereupon.

I have shown one practical embodiment of my invention, and the same may be modified or varied somewhat in different particulars without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-rroo l. Alamp attachment comprisinga burner, a coupling pivotally connected therewith and having means for attachment to the collar of alamp, and oppositely-arranged, annular corrugations on the body of the burner and the coupling, respectively, to cooperate when the burner is closed and form a tight joint between it and the coupling.

2. Alampattachment comprisingaburner, a coupling pivotally connected therewith and having means for attachment to the collar of a lamp, annular grooves and ribs on the upper end of the coupling, and opposed ribs and grooves on the bottom of the body of the burner, to cooperate with each ,other when the burner is closed and form a vapor and oil tight joint, and a device to lock the burner and coupling together when closed.

3. A lamp attachment comprising a burner having a tubular body with a closed bottom provided with peripheral, annular corrugations on its under face, a tubular coupling member having means for attachment to a lamp-collar, a hinge peripherally connecting the upperend of the coupling and the burnerbody, and an inturned, annularly-corrugated flange at the upper end of the coupling, the

ribs and grooves whereof register with the grooves and ribs, respectively, of the annular corrugated portion of the burner-body when the burner is closed, to form a tight joint between it and the coupling.

4. The combination with a threaded lampcollar, of a tubular coupling screwed thereinto, and having its upper end annularly corrugated, a burner having its tubular body hinged to the coupling, a Wick-tube projecting slightly beyond the closed bottom of the burner-body, annular corrugations at the periphery of the bottom, to cooperate with the upper end of the coupling when the burner is closed, and means to cooperate with the lamp-collar and maintain the burner in position when open to move the depending part of the wick toward the side of the coupling, leaving an unobstructed central passage therethrough.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
